LSINITRAMFS(8)

💖 LSINITRAMFS(8) 💖

Okay bestie, this is the manual page for lsinitramfs, the tool that lets you peek inside an initramfs image without unpacking it. ✨

🎀 NAME

lsinitramfs — list content of an initramfs image 🧚

🌸 SYNOPSIS

lsinitramfs [-l] initramfs-file...
lsinitramfs -h

🦋 DESCRIPTION

So the lsinitramfs command lists what's inside whatever initramfs images you point it at. 👀 It's giving quick peek energy. You can check one initramfs file, or a whole bunch of them at once, and see exactly what's packed in there. Main character behaviour, honestly. 💅

✨ OPTIONS ✨

• -h — Shows you the usage info and then exits. Quick and clean. 🫶
• -l — Gives you the long, extra-verbose listing of the initramfs content. If you want all the juicy details, this is your flag. 🔥

🌈 USAGE EXAMPLES

Okay so here's how you'd check the initramfs for the kernel that's running right now:

lsinitramfs /boot/initrd.img-$(uname -r)

And if you want to compare two initramfs files in verbose mode, do this:

lsinitramfs -l /boot/vmlinuz-2.6.31-grml64 /boot/vmlinuz-2.6.33-grml64

💀 BUGS

🙈 Heads up, this one's a little messy. lsinitramfs cannot deal with multiple-segmented initramfs images, except where an early (uncompressed) initramfs with system firmware is prepended to the regular compressed initramfs. So if your image is split into segments, it might not behave the way you'd hope. 😭
